Answer;
-Point D
Explanation;
Two lines intersect when they cross each other. They form vertically opposite angles, which we will learn later. The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines.
In this case line CD and line MD share a common point D, which is a point of intersection of the two lines.
The Point common to each of the two Segments is Endpoint D.
From Geometry we know that a Segment is formed by knowing two distinct Points, which are called Endpoints. If two Lines intersect each other, then there is a Point common to each of the two Segments, which it can be an Endpoint or not.
The set of Endpoints for each Segment are described below:
[tex]\overline{CD} = \{C, D\}[/tex], [tex]\overline {MD} = \{M,D\}[/tex]
As we can see the Point common to each of the two Segments is Endpoint D.
